Two Piece Side Entry

Introduction

The 2-piece design is a widely used valve configuration that consists of two primary components: the body and the end connections. This design offers a simpler, more cost-effective alternative to the 3-piece design, while still providing durability and performance in various industrial applications.

In the 2-piece Side Entry Valve design, the body and the end connections are often welded, bolted, or threaded together. The dimensional details for a 2-piece design are crucial for ensuring the proper fit, leak-proof seals, and reliable operation of the valve system.

Applications

2 Piece Side Entry Valve is trusted across various industries for its precision, durability, and reliability. Explore its wide-ranging applications below:

Oil & Gas icon

Oil & Gas

Ball valves are used in pipelines, refineries, and offshore platforms for quick shutoff and precise flow control under high pressure.

Water Treatment icon

Water Treatment

Ball valves control water flow in treatment plants, dams, and municipal water systems. They're ideal for isolation and regulating water pressure.

Power Generation icon

Power Generation

Ball valves are crucial for steam and cooling water control in power plants, ensuring efficient flow regulation in thermal and hydroelectric setups.

Chemical Industry icon

Chemical Industry

Ball valves offer precise flow control for aggressive chemicals, acids, and gases in processing and manufacturing plants, ensuring safety and reliability.

Pharmaceutical Industry icon

Pharmaceutical Industry

Flow control and isolation valves in pharmaceutical manufacturing processes. The 2-piece design allows for precise flow control and can be easily cleaned, which is crucial for maintaining hygiene and product integrity.

Automotive and Aerospace icon

Automotive and Aerospace

Fuel and exhaust control systems, coolant systems. The 2-piece design provides a lightweight, space-saving solution for controlling fluids in automotive applications, without compromising performance or safety.

Design Features

Double Block & Bleed

Spring loaded floating seats maintain contact with the ball and provide tight shut off even at low pressure differential. Independent sealing of upstream and downstream sides facilities draining of fluid from the body cavity, and thus the double block and bleed operation.

Double Body Sealing

Double seal combination of O-ring and spiral wound gasket ensure perfect body joint sealing. YDB valves therefore meet or exceed the fugitive emission requirements across wide range of pressure and temperature applications.Valves are suitable for both above and underground installations

Fire Safe Design

In the event of fire, soft insert gets burnt and spring loaded seats ensure metal to metal sealing.

Multiple Stem Sealing

A triple sealing arrangement in stem area prevents leakage to atmosphere. It includes double sealing with O-ring and graphite seal at the top of stem housing. The blow out proof stem enables positive stem retention.

Technical Specifications

Within Given Tolerances By Closely Monitoring Critical Dimensions, Surface Finishes, Run Out, Sharp Edges Etc. After Referring And Meeting The Requirements As Per Drawing, Under Rigid Quality Controlled Procedures Approved To ISO 9001: 2015 Which Ensures Consistent Quality and High Performance Products.

Corrosion Protection and Painting

  • ✔All castings are shot blasted and are subjected to dewatering oil coats. Carbon Steel valves are zinc phosphated and internally lacquered before final assembly.
  • ✔Valves are thoroughly cleaned and primer coated with Epoxy Zinc Phosphate primer, followed by a final coat of Epoxy Blue shade applied in semi-gloss finish.
  • ✔Valves are shipped in vapour corrosion inhibitor impregnated paper bags with desiccant pouches to prevent corrosion due to saline environment.
